Effects of Hydrotreatment on the Composition of Mutagenic Fractions of a Coal-Derived Petroleum Substitute

摘要

Coal- and shale-derived product oils differ from petroleum crudes by being more highly aromatic and by containing a greater quantity of heteroatomic species. Catalytic hydrogenation (hydrotreatment) is commonly used to improve both handling and use properties. In this study, the basic and neutral polar compounds of a crude coal derived liquid and three products from this crude which have been subjected to low, medium, and high severity hydrotreatment have been isolated and chemically characterized to determine whether hydrotreatment resulted in a selective reduction of a few N-containing and aromatic components or a general reduction of all components. 8 tables.
